Crouan’s type has not been seen but authentic specimens from 
M. C. Cooke’s collection have been examined and found to agree 
with American specimens referred to this species. One collection 
in great abundance was made near New York City during the 
past season. 
2. Lamprospora dictydiola Boud. Hist. Class. Discom. 68. 
1907 
Plants gregarious or scattered, not crowded, expanding with 
the hymenium, becoming plane or nearly so and bordered with 
a delicate, ragged, fringe-like margin and more or less pitted and 
roughened, entirely orange without and within, about 1 mm. in 
diameter (in the living specimens examined) ; asci cylindric or 
subcylindric, about 18-20 /a in diameter and of variable length; 
spores 1 -seriate, at first smooth and usually with one large oil- 
drop, at maturity becoming very delicately reticulate, meshes of 
the reticulations 1 ^ or less in diameter and ridges appearing as 
single lines (when examined with a one sixth objective) ; entire 
spore 12-15 /a i n diameter, hyaline; paraphyses enlarged above 
reaching a diameter of 5 n, nearly straight or occasionally a little 
curved, never hooked as in some related species. 
On charcoal which has been overgrown with mosses. 
Type locality: Montmorency, France. 
Distribution: New York; also in Europe.

Our specimens conform well with the illustration of this species 
by Boudier. The species has been collected twice but in each 
case not over two or three plants were found. 
3. Lamprospora areolata Seaver, Mycologia 4: 48. 1912 
Plants gregarious, small, .5-1 mm. in diameter, at first globose, 
opening rather irregularly, at maturity with the hymeiiium plane 
or slightly convex, more or less roughened by the protruding asci, 
orange to bright red; asci cylindric, 15-22 /t in diameter and of 
variable length, tapering below into a stem-like base; spores 
i-seriate, at first smooth, with usually one large oil-drop, becom- 
ing rough at maturity, roughenings taking the form of deep 
areolations, areolae 3-5 /a in diameter, 3-6-sided, often forming
